Parallel to the legitimate world of international commerce and finance, there exists an alternative universe of commercial fraud. From Charles Ponzi to Bernard Madoff, commercial fraud is a matter of the gravest concern because, apart from direct and indirect losses, it poses a serious threat to the integrity of the economy. One of the significant problems in dealing with it is the lack of a systematic study of its nature and of the role of law in combating it. This course studies commercial fraud from the perspective of financial fraud, commodity fraud, and fraud regarding the sale and delivery of goods, consumer fraud, securities fraud, bank fraud, risk management, insurance, and money laundering, touching on issues in commercial law, contract, tort, and regulatory matters as well as criminal law.
